Dealing with project reserves: Insights into the project circumstances that influence the estimation and expenditure of project reserves in Dutch road-widening projects

The Role of Subjective Well-Being in Co-Designing Open-Design Assistive Devices; design case study

In this paper we explore the role of subjective well-being within the process of making together a personalized assistive device. Through a process of social product adaptation, assistive artifacts become part of occupational therapy and co-evolve with clients. Personal digital fabrication tools enable small user groups to make and share their...

Positive design: An introduction to design for subjective well-being

This paper addresses the question of how design can contribute to the happiness of individuals–to their subjective well-being. A framework for positive design is introduced that includes three main components of subjective well-being: pleasure, personal significance and virtue. Each component represents an ingredient of design for happiness, and...

Design for Political Involvement - Reframing the party-citizen relation

This thesis describes the process and results of the graduation project “Design for Political Involvement” for the Masters’ course Design for Interaction. The project was executed for the political party D66. The goal of the project was to design a product that will increase the involvement of citizens in the political party D66 by the year 2018...

Does migration make you happy? A longitudinal study of internal migration and subjective well-being

Marie Curie programme under the European Union's Seventh Framework Programme (FP/2007-2013) / Career Integration Grant n. PCIG10-GA-2011-303728 (CIG Grant NBHCHOICE, Neighbourhood choice, neighbourhood sorting, and neighbourhood effects). The majority of quantitative studies on the consequences of internal migration focus almost exclusively on...

Een andere manier van gebiedsontwikkeling: Nieuwe waardedragers?

Analyse of problem In the fall of 2008 the credit crunch started in The Netherlands. The financial sector in The Netherlands deteriorated with serious consequences for the Dutch real estate market. After years of increases in real estate investment, the investment volume in Dutch real estate decreased in the second half of 2008 (Debenham Thouard...

Interactions of visual attention and quality perception

Several attempts to integrate visual saliency information in quality metrics are described in literature, albeit with contradictory results. The way saliency is integrated in quality metrics should reflect the mechanisms underlying the interaction between image quality assessment and visual attention. This interaction is actually two-fold: (1)...

Estimating the impact of single and multiple freezes on video quality

This paper studies the impact of freezing of video on quality as experienced by users. Two types of freezes are investigated. First a freeze where the image pauses, so no frames were lost (frame halt). In the second type of freeze, the image freezes and skips that part of the video (frame drop). Measuring Mean Opinion Score (MOS) was done by...

Does Migration Make You Happy? A Longitudinal Study of Internal Migration and Subjective Well-Being (discussion paper)

The majority of modelling studies on consequences of internal migration focus almost exclusively on the labour market outcomes and the material well-being of migrants. We investigate whether individuals who migrate within the UK become happier after the move than they were before it and whether the effect is permanent or transient. Using life...

Design for subjective well-being

Happiness is often considered a universal goal of people. In the relatively new field of positive psychology, many studies have been conducted to understand the concept of happiness and its broader counterpart; subjective well-being, leading to a collection of theories that explain their determinants. It has been shown that although there are...

Comparing subjective image quality measurement methods for the creation of public databases

Model validation of channel zapping quality

In an earlier paper we showed, that perceived quality of channel zapping is related to the perceived quality of download time of web browsing, as suggested by ITU-T Rec.G.1030. We showed this by performing subjective tests resulting in an excellent fit with a 0.99 correlation. This was what we call a lean forward experiment and gave the rule of...

Of MOS and men: Bridging the gap between objective and subjective quality measurements in mobile TV

In this paper we explore the relation between subjective and objective measures of video quality. We computed objective MOS values from video clips using the video quality measuring tool VQM and compared it to the clips’ subjective Acceptability scores. Using the ITU defined mapping (M2G) from MOS to binary Good or Better (GoB) values, we...
